Custom BLDC Motor Controllers

Custom BLDC Controllers

A BLDC motor controller is an electronic device responsible for regulating the operation of BLDC motors. More specifically, it controls the torque and speed of the motor and can also start, stop, and reverse its rotation.

These devices often sense the rotor’s position using sensors; however, sensorless options are also available. Once the sensors identify the position of the rotor, they transmit this data to the controller, which subsequently instructs the transistors to switch the electrical current and energize the appropriate stator winding at the proper time.

Typical BLDC motor controllers have a half-H bridge or half-bridge circuit. Compared to H bridge circuits, this configuration only has two switches – one low-side and one high-side transistor. BLDC controllers are similar in structure to brushed DC motor controllers. Apart from being brushless, the primary difference is that BLDC controllers have three phases, with at least two transistors per phase.

Due to the complexity of BLDC motor controllers, it’s important to work with an experienced provider like Composite Motors. We can deliver quality, customized BLDC controllers for everything from industrial robots and electric vehicles to computer hard drives and more.
